2. Clinical efficacies of resurfacing and non-resurfacing patella in total knee arthroplasty for osteoarthritis: A meta-analysis
Academic Journal of Second Military Medical University 2011;32(5):504-509
Objective: The compare the clinical efficacies of resurfacing and non-resurfacing the patella in primary total knee arthroplasty (TKA) in osteoarthritis patients, so as to provide evidence for clinical practice. Methods: A comprehensive search for relevant studies was performed in PubMed (January 1966 to December 2010), EMBASE(1969 January to December 2010) and the Cochrane Libray databases. Only randomized control trials comparing the outcomes (incidence of anterior knee pain, revision rate, and reoperation rate, etc.) of resurfacing and nonresurfacing patella in patients undertaking primary TKA were included in the present analysis. Results: Nine independent randomized clinical trials were finally identified. Analysis of these trials showed that patellar resurfacing failed to make difference in incidence of anterior knee pain, revision rate, or reoperation rate compared with the non-surfacing group. Conclusion: Patellar resurfacing can not reduce the incidence of anterior knee pain, revision rate, or reoperation rate in patients undergoing primary TKA, and therefore can not contribute to a better outcome in these patients.
3.Effect of Budesonide on Dendritic Cells in Asthmatic Mice
Journal of Applied Clinical Pediatrics 2006;0(16):-
Objective To explore the effect of budesonide(BUD) on dendritic cell(DC) and airway inflammation in the asthmatic mice.Methods Forty female Kunming mice were divided into 4 groups:asthmatic model group,therapeutic control group,BUD treated group,and normal control group,with 10 mice in each group.Mice were sensitized by an intraperitoneal injection of 50 ?g ovalbumin(OVA) adsorbed to 1 mg aluminum hydroxide dissolved in 0.2 mL saline.Animals were boosted on the 14th day in the same way.From the 21th to 35th days,and mice were challenged with 10 g/L aerosolized OVA for 30 min a day to establish a murine model of asthma.To evaluate the effect of BUD,60 minutes prior to OVA exposure,the mice were treated with 1 mg aerosolized BUD or placebo(saline).Control animals were sensitized intraperitoneally with saline and challenged with aerosolized saline alone.Eosinophil(EOS) count,degree of mucus secretion and DC count around the airways were measured by haematoxylin and eosin staining,periodic acid schiff's staining,immunochemistry technique and computerized image analysis system.Results In asthmatic model group,EOS count,DC count and the degree of mucus secretion around the airways were increased compared with nomal control group(P_a0.05).In BUD treated group,EOS count,DC count and the degree of mucus secretion around the airways were decreased compared with the asthmatic model group(P_a

Objective To investigate the current status of coal-burning endemic fluorosis and the fluoride content in foods and drinking water in Hongya County,Sichuan Province.Methods Dental fluorosis and urinary fluoride were suveyed in children of 8~12 years old in two schools which repectively located in Gaomiao and Wawushan Town.The adults above 20 years old underwent clinical examination.At the same time,fifty adults above 20 years old in Garden Village were chosen to take forearm and calf X-ray films to find out the evidence of skeletal fluorosis.The content of fluoride in food such as bacon,corn,dry capsicum in Sanxing Village in Gaomiao Town and Futian Village in Wawushan Town as well as drinking water in five families in Sanxing Village were determined.Results The dental fluorosis rate of children was 40.76%(161/395),the dental fluorosis index was 0.86 in Gaomiao Town.The dental fluorosis rate of children was 14.36%(82/571),the dental fluorosis index was 0.31 in Wawushan Town.The medium value of the urine fluoride was 0.81 mg/L.ranged 0.16~3.89 mg/L.The positive rate oi the clinical examination of skeletal fluorosis was 5.27%(27/512),the X-rays detective rate was 4.00%(2/50).The medium value in bacon,corn,dry capsicum were 6.00,0.64,1.49 mg/kg.The averaged content of the fluoride in drinking water(0.14±0.06)mg/L of local household was within the eligible limitation.Conclusions It is currently a mild endemic disease in Hongya Country,its incidence is reduced apparently,pathogenetic environmental fluoride content is reduced.The main source of fluoride is from the preserved ham contaminated with fluoride,which is epidemiologically significant in endemic area of Hongya County.Defluoriding countermeasures should be taken in the endemic areas.

ObjectiveTo campare the quality of life of schizophrenics treated with aripiprazole or clozapine.Methods90 cases with schizophrenia were randomly divided into aripiprazole group and clozapine group.After 6 mouths of treatment,all subjects were assessed with Positive and Negative Syndrome Scale(PANSS),WHO QOL-100 and Treatment Emergent Symptoms Scale(TESS).ResultsAripiprazole could significantly improve all aspects of quality of life except domination,and had a better result in physical,psychological,level of independence,solial relations,environment domain than clozapine did.Clozapine could only improve psyclological domain.There was no significant difference between the score of PANSS in two groups.However,aripiprazole had a better result in negative symptoms.ConclusionSchizophrenic outpatients treated with aripiprazole have a better quality of life than those with clozapine.

Objective To study the effect of astragaloside on proliferation and apoptosis in human keloid fibroblasts.Methods The human keloid fibroblast ceils were treated with different concentration of astragaloside(10、20、40 ng/mL).Cell proliferation was detected by MTT,the gene expreesion levels and protein levels of apoptosis-related proteins,survivin,p53 and Bcl-2.were determined by real-time PCR and Western blot,respectively.Results Comparecl with control group(treated with 0 ng/mL astragaloside),the absorbance values (A490 nm) of each concentration group were significantly reduced,which suggest that the proliferation of all keloid fibroblast were markably inhibited in a dose-dependent way (P<0.05).The gene expreesion levels and protein levels of apoptosis-related proteins,survivin、Bcl-2 were largely suppressed and P53 werelargely promoted in a dose-dependent.Conclusion The keloid fibroblasts cells proliferation and apoptosis could be regulated by astragaloside.

Posterior capsule opacification (PCO) is the most common complication after cataract surgery.How to prevent and treat PCO is an urgent problem we need to solve at present.Non-coding RNA(ncRNA) is a kind of RNA, which can not encode proteins.Studies have shown that non-coding RNA is closely related to the occurrence and development of human diseases.This paper has collected the progress of research on different kinds of ncRNA in PCO and may raise new ideas and methods on the prevention and treatment of PCO.
